HI-FIRE 1550 Electrically Operated Kilns

Construction

The bench mounting pressed steel cabinet formed with removable side and top panels, suitably louvered for ventilation purposes. The pressed steel door is hinged on the left side and the whole cabinet sprayed with an undercoat sealer and attractive gloss finish.

Lining

This comprises a mixture of vacuum formed ceramic fibre modules and where necessary high grade insulating brickwork for maximum thermal efficiency. A solid refractory insulating brick base is formed to support the work load.

Elements

These comprise Silicon Carbide type resting horizontally between the front seal and the rear wall of the kiln. Lead out tubes are used through the rear wall with braids clamping onto the element cold ends, leading to terminal posts in the rear connection chamber.

Controls

Micro processor based digital readout ramp programmer works in conjunction with phase-angle thyristors for infinite control of power relative to required firing cycle. To overcome element ageing problems kiloWatts per phase can be checked at any time by observation of an analogue type Wattmeter which operates in conjunction with trimmers via a multi point selector switch. When kilowatts decrease, the trimmers can be adjusted accordingly, taking the power back to the original setting.

To avoid an overfire situation, a “Policeman” non-indicating type temperature controller is fitted as standard. Thermocouples/compensating leads etc. are all interwired at factory.

Safety

A door operated electro-mechanical type interlock is fitted as standard.

Optional Extras

These include alternative types of programme controllers, temperature recorders, etc. Fully illustrated leaflets available on request.
